help I am lost and confused and need to know if i would be the azzhole if I cut off my dad

first I want to thank Charlotte for being a away for me to escape when ever things have been way to much for me. I also have no idea were to go and ask for advice on this so I am hoping I can get some with the love followers Charlotte has. Anyway on with whats going to be a long story that I need advice on. so last year a while before Thanksgiving I got a bunch of calls from my mom and my sisters that I missed due to me being asleep. when I called my mom back she asked me if I was at work and I told her no I had the day off she then asked if my partner was home as well which concerned me even more but I told he was. at which point she told me my father had been arrested for certain things that I will not dive to into due to what they are but I will say it involved asking for things from a certain age group...

I was having a hard time trying to believe the man I called dad would do something like this and if he had how did I not see it. I had called my sisters and talk to them to make sure each was okay 1 was okay for the most part very shaken and railed by the fact swat showed up but she didnt have to deal with them tell she got home from school while my other 2 were terrified of what was happening.(for the safety of my sisters and mom i will use fake names due to the fact the news wrote about my father. so the sister under me will be kiera the next will be hope and the baby will be Kat. my mom will just be my mom.) kiera told me how terrified she was to be woken up having swat banging on her bedroom door yelling at her to come out. while hope said she had to let them in and they kept both her and kiera away from our father. while kat seemed to be doing okay for the most part just more confused and lost on what was going on.

you may ask why was my mom not there well she was at work and when koera or hope tried to call her they were shut down. so when they finally were able to and she got there she felt very upset that her home no longer was a safe space for anyone. as time went on we learn more and more about things my father had done such as giving information about my sisters and I to other people who liked the same things he was doing or tell family they could not spend time with us becausethey would currupt us. throughout the trial as more and more came out the figure I thought was my dad kept shattering and my sisters and I started to relise just how toxic of a dad he was. I remember I was the one who always tried to make sure he never said or physically hurt my sisters but sadly I dont think I was able to stop all of it. as they have all told me things he had said and did that I wish I could have stopped.

now I am the only one he can talk to or his parents can talk to me about him. my sisters and mom have a protective order against him. they also are all in therapy and seem to be doing okay for the most part. however I have some major concerns still that my dad did something more physically with all 3 of my sisters due to the fact that kiera has issues with trying to be in any relationship very physically and shows some tendencies that he may have done something to her. hope hates men and has shared with me that she hated our father for a long time due to all the horrible things he would say to her about everyone including herself that really damaged her confidence and she is so disgusted by the topic of certain physically things that she explained it to me as when she hears or talks about them she want to bleach and scrub her body raw. and kat has lashed out more and we have noticed some other things as well as told us that she had something happen at school that caused her to have to make a decision she shouldn't of had to make as a teenager and our dad new about it and told her it was her fault for it happening.

so on to what I need advice on I am struggling with coming up with and setting boundaries with the man I called dad. I currently have one were he can not call me he can only write me due to the fact when I would call him I felt even worse after talking to him. and I still have that with some of his letters but he never gets to hear or see my reaction just what I want him to know. he wants to rebuild a relationship and I am not sure how to? because before this happened he had cheated on my mom with 12 plus women. and I was the one who had to tell my mom and show her everything. and the only reason she stayed was because kiera's and Kat's therapist told her they would probably commit sluwicid if she divorced him.(I really want to laugh in that therapist face right now and say well she's almost losing all her kids now after she stayed with him.) which almost broke me. seeing what it did to my mom and sisters when she kicked him out that time.

now that he has done this hence thing I have no idea how I can try to have a relationship with him. he cant be apart of my life or any of my kids life because of his charges. my partner wants me to just cut him off and wants me to have nothing to do with him. I just dont know if I can or am ready for that yet. but I am struggling to see how he can be apart of my life with what he has done. so what should I do? would i be a azzhole if I did cut him off or should I try to see if I can have some sorta relationship with the man i though was supposed to be my father and Proctor from people like him?
